摘要:
A holographic display comprises a source of coherent light and an Electrically Addressable Spatial Light Modulator (EASLM) in the path of the light source. The EASLM is arranged in use to be driven successively by a set of sub-holograms which together correspond to a holographic image. Light guiding means is arranged to guide light output from the EASLM such that the sub-holograms are displayed successively in respective tiled regions of an EASLM projection surface.

A holographic display comprises a light source and an Electrically Addressable Spatial Light Modulator (EASLM) (1) in the path of the light source. A light guiding means (4) is arranged to guide light from the EASLM to each of a set of tiled regions of a OASLM (8) in turn. The Optically Addressable Spatial Light Modulator (OASLM) has a monostable light modulation property which is changed from a first state to a second state by incident light.

An acousto-optic device (10) having a wide range of diffraction angles and an optical scanner, a light modulator, and a display apparatus using the acousto-optic device are provided. The acousto-optic device (10) includes a core layer (11) having a periodic photonic crystal structure in which unit cells of predetermined patterns are repeated, a first clad layer (12) on a first surface of the core layer (11), the first clad layer (12) having a refractive index that is different from the refractive index of the core layer, a second clad layer (13) on a second surface of the core layer (11), the second surface being opposite the first surface, the second clad layer (13) having a refractive index that is different from the refractive index of the core layer, and a sound wave generator (14, 15, 16) configured to apply surface acoustic waves (SAW) to the core layer, the first clad layer, the second clad layer, or any combination thereof.

An acousto-optic device includes an acousto-optic medium having a multi-layer nanostructure; and a sonic wave generator configured to apply sonic waves to the acousto-optic medium having the multi-layer nanostructure. The acousto-optic medium having the multi-layer nanostructure includes a second layer formed of at least two materials that have different dielectric constants and alternate with each other; and a first layer disposed on a first surface of the second layer and formed of a first material, and/or a third layer disposed on a second surface of the second layer and formed of a fourth material.

A gaming machine including a controller coupled to a 3D display that displays true 3D or virtual 3D imagery associated with a basic or a bonus wagering game. 3D displays can display true 3D imagery or virtual 3D imagery that is displayed in 2D but perceived by the viewer to be 3D. True 3D displays include a volumetric 3D display, a multi-layer display, and a holographic display. Virtual or stereoscopic displays include a lenticular display employing cylindrical or spherical lenslets, a parallax illumination display employing light lines to create a parallax effect, or non-autostereoscopic displays requiring a special viewing aid to complete the 3D effect.

摘要:
A holographic display device and a method for generating a hologram are disclosed. The holographic display device generating a hologram includes a storage unit (180) and a control unit (190). Herein, the storage unit stores at least one look-up table each storing a partial size (400, 600) of a full size (300,500) sub-hologram for reconstructing object point (OP), wherein the object points (OP) are included in a scene reconstructed by the generated hologram. And, the control unit uses at least one look-up table each having the partial size, so as to calculate hologram values for the sub-holograms for reconstructing object points (OP), wherein the object points (OP) are included in the scene, and then the control unit generates the hologram by overlapping the hologram values of the sub-holograms.
